Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed September 80, 1915. Serial No. 58,879.

To all whom it may concern Be it known that we, Jo'HN SELLERS BAN- CROFTand MAURITZ C. INDAHL, citizens of the United States, residing atPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Shearing Mechanismfor Lead and Rule Strip Casting Machines; and we do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompan ing drawings, forming part of thisspeci cation.

The present invention relates to apparatus for producing printers leads,rules, borders, or printing elements of similar character, and moreespecially to mechanism adapted to produce the printingvelements by an111- termittent action, but in indeterminate lengths, the object of theinvention being to provide a means whereby the strip may be severed intolengths which may be accurately predetermined, thus adapting the machinefor delivering printers leads or rules, for example, of any desiredlength within the capacity of the machine, and eliminating the necessityof hand shearing, such as has heretofore been necessary to make theleads and rules fit the forms or make-up for printmg.

The invention, while not limited thereto, is primarily adapted for usein connection with Lanston monoty e casting machines, such, for example,as t at set forth and described in Letters Patent No. 625,998, grantedto J. S. Bancroft, May 30. 1899, as modified and adapted for the castingof leads, rules, etc., by intermittent operations of casting andfeeding, the machines so modified being now in commercial use and thenovel features are set forth in a contemporaneous application forpatent, filed in the name of Amos L. Knight, on October 3, 1914, SerialNo. 864,894.

The invention consists primarily in combining with an intermittentlyacting lead and rule casting machine for producing a stri ofindeterminate length, a shearing mec anism actuated through powerconnections with the driving mechanism of the casting machine, butcontrolled by the strip produced thereby in such wise that theshearingmechanism for severing the strip op crates when the strip is at rest,thus insuring the cutter operating ing accuracy in the length deliveredwith means whereby such length may be varied at will for the roductionof leads or rules of any desired ength, or to fit the work in hand.

The invention further consists in a shearng mechanism in which thecutting device s moved in unison with the strip by a age interposed inthe path of the strip an the cutting operation performed at any oint inthe length of the strip as determined by the d stance between the gageand cutting de vice.

The invention further consists in certain novel details of constructionand combinations and arrangements of parts, all as will be hereinafterdescribed and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a front elevation ofa portion of a Lanston monotype casting machine, many of the partshaving no s ecial relation to the present invention being omitted, andparts relating to the present invention added. Fig. 1' is a viewcorresponding to Fig. 1 and showing those portions of the machine to theright of the portions shown in Fig. 1, the two views Figs. 1 and 1"being intended to illustrate in front elevation the machine embodyingthe present improvements, omitting only the fixed table on whichtheleads and rules are delivered from the shearing mechanism. Fig. 2 isa sectional elevation looking toward the left in Fig. 1 and showing thelead and rule guide, the operating mechanism therefor, the lead and rulesupport, and the movable table, the fixed table being shown in dottedlines. Fig. 3 is a view corresponding to Fig. 2, but omitting the guidesand their support and showing, in addition, the cutter 0 rating and leadtransferring mechanism. ig. 4 is a front elevation showin on an enlargedscale portions of the. mec anism shown in Fig. 1. Fig. 5 is aperspective view showlever and lever which is carried thereby foroperating the guide. Fig. 6 is a perspective view showing the cuttercarriage, cutter and adjustable gages for regulating the length of leador rule to be delivered. Fig. 7 is a sectional plan thron h a portion ofthe mechanism shown in ig. 6, together with the guide roller forsupporting the lead or rule strip at the point where it enters thecutter carriage. Fig. 8 is a detail plan view of the adjustable gagemechanism shown in Fig. 6. Fig. 9 is a Sectional elevation substantiallyin a plane indicated by the line 99 in Fig. 1 t e spring at the lefthand end being shown in dotted lines. tive view of a art of the bellcrank lever for operating t e cutter. Fig. 11 is a perspectlve view ofthe trip mechanism for releasing the inte onent to effect the operativeconnection etween the operating or power lever and the bell crank lever.

Like reference characters in the several figures indicate the sameparts.

The mechanism illustrated as the preferred embodiment of the presentinvention is designed for use in connection with a Lanston monotypecasting machine and in order that the relationship of the parts may beproperly understood from the accompanying drawings, there are shown inFigs. 1 and 1' in a conventional manner, certain parts of the monotypemachine which Wlll be at once recognized by those .skilled in the art.The mam frame of the machine is indicated by the reference numeral 1;the cam shafts by the numeral 3; the drive shaft by 4; the leveroperated by cams on the cam shaft for reciprocating the mold blade, by5; the bracket which carries the galley by 6; the vertically adjustablemelting pot and its supporting bracket by 7 and 8, respectively; and thenozzle through which the molten metal is injected into the mold cavityby the dotted lines at 9.

In the production of printers leads or rules in the form of a strip ofindeterminatelength, the molten metal is injected into the mold cavitybetween the end of the mold blade and the congealed ortion of the metalpreviously injected. his portion of the apparatus, in so far as thespecific construction is concerned, is the invention of Amos L. Knightand is embodied in the before-mentioned application. In the presentillustration the more or less diagrammatic showing is thought to besufficient to illustrate the operation of forming and feeding the strip.By reference to Figs. 1 and 1" it will be seen that the lead or ruleindicated at 10 has been formed by the injection of metal fed forwardintermittently by the reciprocation of the mold blade 11 through themedium of the operating lever 5 and connections 12 intermediate saidlever and mold blade, a portion of which connections are shown brokenaway. Metal havin been injected through the nozzle 9, congea s, and bythe next forward movement of the mold blade 11, it is advanced into aposition which will permit of the formation of a cavity for the nextincrement of metal when the mold blade is withdrawn. Each incre- Fig. 10is a perspecthrough the nozzle 9 and ment of metal, fuses with the metalpreviousl injected, thus uniting the lead or rule in the form of a longstrip which is intermittently advanced and is guided to the cuttingmechanism where it is subdivided into sections of the desired length.

Through mechanism which will be presently described the cuttingmechanism is preferably operated in such wise that, when the actualseverance is effected, the lead or rule is stationa and the power foroperating the cutter is preferably derived from one of the cam shafts 3.Said cam shaft is provided with cam 13 upon which rides an anti-frictionroller in the shorter arm of an operating lever 14, pivotally mounted ina bracket at the front of the main frame or stand 1, and with its freeend projecting a short distance beyond the meltin pot 7.

The cutting or shearing mechanism, except for the parts hereinbeforedescribed is all adapted to be mounted upon or carried by the bracketwhich supports the melting pot, and is movable in unison therewith intoand out of its operative position, and to adapt it for application tothe standard monotype machine, it preferably embodies a vertical bracketor frame 15 which is adapted to be secured to the melting ot bracket bybolts 16 or other appropriate astening means, and at its upper end tosupport a rigid horizontal bar or extension 17. The entire shearingmechanism per 86 is mounted on the bracket frame 15 and its extension17; thus the entire mechanism may be readil applied or removed.

Extending own from the part 17 are two supporting arms 18, the lowerends of which carry a horizontal track or way 19 upon which the loweredge of the lead or rule strip ma travel. intermediate the mold and theway 19, by a guide roller 20, best seen in Fig. 7 and adapted to beadjusted by a movement of its eccentric support through the. medium of ahandle 20 at the front of the frame 15. The shearing or cutting devicesare mounted to move parallel with the strip intermediate the guide 20and the way 19, and said shearing or cutting devices preferably embody acarriage or frame 21 having top and bottom guide surfaces 22 tocooperate with corresponding surfaces formed in the rojections 23 of thebracket frame 15. he carriage 21 may conveniently be called a slidingcutter frame, and mounted within it in suitable bearings is atransversely movable knife or cutter 24, said cutter being adapted tointersect the end of the opening 25 through which the strip passes andby the cooperation of the movable cutter'24 and one wall of the opening25, which is in effect a fixed cutter, the severance of the strip iseffected. I}

In order to locate the cutter with respect 10s The strip is supported tothe end of the strip, whereby the accuracy of the length of stripsevered may insured, the sliding cutter frame is provided with a longand preferably square gage rod 26 conveniently guided at its outer endin a guide formed on the extremity of the way 19 and upon this gage rodthere is mounted an adjustable gage, with which the end of the lead orrule strip is ada ted to contact and whereby the cutting evices will bemoved in unison with the strip, for a limited distance. The gagepreferably employed embodies a clamp collar 27 .adapted to be set in anydesired position of adjustment in the length of the rod 26, and a slide28 having collars 29 embracing the rod 26 with i an interposed spring 30for holding the slide 28 advanced. The slide 28 carries a ge or bracketin position for the end of t e lead to contact therewith, and in thispreferred construction it carries two of such gages or projections,thatindicated at 31 being;

he turned pivotally mounted so that it ma from the position indicated inull lines to that indicated in dotted lines in Fig. 8, while that at theopposite or outer end of the slide is a rigid gage or projection 32. Thepivoted gage or bracket 31 is held in its adjusted position by aretaining collar 33 held advanced by the spring in position for itslateral projections 34 to bear yieldingly against one or the other ofthe flat surfaces of the gage, thus forming a type of well knownretaining devices conveniently adapted for the particular situationwhere now employed. Obviously, by the use of one or the other of theprojections 31, 32, the range of lengths into which the strip may be cutis considerably increased.

All of the movable parts of the shearing and cutting mechanism which aremoved by and in unison with the lead or rule strip must be made as lightas ossible, inasmuch as it is frequently desira le to cut exceedinglythin strips, the strength of which would be insufficient to move thecutter if of heavy construction, or, if suiiicient to move these parts,the strip itself would be deformed, either at the end or by buckling atan intermediate point. For the reasons stated and others, it isdesirable that the cutters be afforded the greatest freedom of movementin unison with the strip, and this has necessitated the provision ofmeans whereby the transversely movable knife may be connected with itsoperating mechanism without imposing a load on the strip itself. In thepreferred construction, a forked operating lever 35 is provided, saidlever being ivoted at its upper end on the frame 15 an provided at anintermediate point with a horizontal shaft or pin 36, passing through aneye or bearing 37, Figs. 6 and 7, in the rear end of the knife or cutter24. The length of the pin 36 between the arms of the lever 35 issuflicient to permit of a full movement of the cutter frame in unisonwith the strip and a slight overthrow, should the momentum of the partscarry the cutter frame awayfrom the end of the strip. The lower end ofthe forked lever 35 is normally held in position with the knife orcutter 24 retracted, by a spring 38 and movement is imparted to it foradvancing the cutter 24 by a bell crank operating lever 39 having a camface or wiping surface 40 cooperating with the lower end of the lever35, the normal position of the two levers being determined by anadjustable stop 41. Movement is imparted to the lever 39by the longoperating lever 14 hereinbefore referred to and the connection betweenthe 0 rating lever 14 and bell crank operating ever 39 is effected by aninterponent 42 under the control of the lead or rule strip through themovement imparted by the latter to the gage and sliding cutter frame orcarriage. The mechanism for effecting such control embodies a releasingand resettin latch mechanism for the interponent and a ever operated bythe sliding cutter frame for operating the latch mechanism, such partsbeing best seen in Figs. 1", 3, 4, 10 and 11. By reference to Fig. 4 itwill be seen that a light lever 43 is pivotally mounted on the bracketframe 15 at a point intermediate the length of the lever, the upper endof said lever being in position to be moved by the sliding cutter frame21 whenever the gage is advanced by the lead or rule strip.a The lowerend of the lever 43 projects tween the proximate faces of a pair ofescapement pawls 44 and 45, normally held toward each other by aninterposed spring 46 and both, together with the lever 43, normally heldwith the upper end of the lever against the cutter frame 21 by a spring47, the outer end of which is secured to a downwardly extending'fixedarm 48. The lower ends of the escapement pawls 44 and are provided withshoulders 44' and 45, adapted to serve as stop shoulders for the upperend of a bolt 49, the lower end of which bolt is pivotally connectedwith a bell crank lever 50, mounted on a pin carried by the latchoperating bell crank 39. The other arm of the small bell crank lever 50is adaptedto contact with a pin or rod 51, extending through a suitableguide 52 and jointed to the interponent 42, see Figs. 3 and 10. A spring53 holds the 'bolt, interponent and bell crank lever 50 toward eachother, and a spring 54 connected at its upper end with the frame orbracket 15 normally tends to elevate the bolt 49 and to advance theinterponent 42 from the position shown in full lines to the positionshown in dotted lines in Fig. 3. The upward movement of the bolt 49 is,however, normally prevented b the escapement pawl 45, against the shouof which the bolt seats, as shown in spring 47 to swing the escapementpawl 45 away from the end of the bolt 49, with the result that the bolt49 moves upwardly and the interponent 42 swings out under the operatinglever 14. Upon the descent of the operating lever 14, the bell cranklever 39 will bedepressed at its outer end, the lever 35 will be swunginwardly, and the knife or cutter 24 advanced to sever the strip. Thedownward movement of the outer end of the bell crank lever 39 draws thebolt 49 downward and the moment the upper end of the bolt passes theshoulder 44 on the escapement pawl '44, the latter swings inwardly underthe influence of the s ring 46. U on the return movement of tiieoperating ever 14 taking place, the bolt is held down and theinterponent swung back from the dotted line to the full line position,or to approximately the full line position, for the shoulder 44" is avery slight distance below the shoulder 45 and the end of the bolt istransferred from one shoulder to the other, by the return of the slidingcutter frame and lever 43 to normal position under the influence of thespring 47.

From the foregoing it will be seen that the only load imposed upon thelead or rule strip in order to set the cutting mechanism in position tobe operated from the power connection, is the inertia of the slidingoutter frame, the lever 43 and escapement pawl 45 with the tension ofthe sprlng 47. All of the arts referred to may be made exceedingij lightand the tension of the spring adjusted so that it will yield under avery slight ressure, but at the same time the tension of the springshould be sufficient to insure the return of the sliding cutter frameand parts carried thereby to normal position, ready for a subsequentoperation and to hold the age in proper engagement with the end of t estrip.

The lead and rule strip after passing through the sliding cutter frametravels along on the guideway 19 and between sup-.

porting ides and 55", see Figs. 1", 2 and 9. hese supportin guidesare 1nthe form of bars arranged a ove the ldeway 19 and carried on the lowerends 0 hangers 56 and 56 depending from a horizontal shaft 57 supportedb the arms 18 and forming a journal for t e said hangers. The hangersare held toward each other with the supporting guides in proper normalrelation by an inter osed tension s ring 58 and both hangers an guidesare he d in position over the guideway 19'by spring 59, but are capableof being swung either together or there be any tendency for thedifferent distances toward the front of the machine, for example, shownin full lines to that shown in dotted lines in Fig. 2. When so moved,the strip held between the guides55 and 55 will be moved transverselyoff of the guideway 19 and permitted to drop on to the swinging section60 of the supporting table, as will be hereinafter described. Foroperating the supporting guides and insuring the proper support of thestrip while it is being fed forward and adjusting the cutting mechanismand also for insuring, the release of said strip when the supportingguides are swung oil to one side by opening the guides and releasing thestrip, should same to stick, an operating lever 61 is pivotally mountedon the end of the bolt or in 36 which advances the laterallyv mova leknife or cutter, and this lever 61 is provided with three arms, thelower arm 61" being adapted to contact with a rocker 62 to be presentlydescribed, while the intermediate arm 61 is adapted to contact with thesupporting guide 55", and the upper arm 61 to contact with the hanger 56of the guiding support 55. The relation of the as the forked lever 35swin s inwardly, the movable knife or cutter is rst advanced to severthe strip, whereupon the lower arm 61 of the lever 61 strikes the rocker62, whereby its forward movement is arrested and the upper arms of saidlever come into contact with the guiding support 55 and hanger 56 tomove said guiding supports laterall The guiding support 55 is moved aconslderably greater distance than the guiding support 55, whereb thetwo are .Separated so as to permit 0 the free discharge of the severedsection of the stri To insure the discharge of the strip should there beany tendency of the same to stick against the face of the guidingsupport 55, a series of fingers 63 are secured to the guiding support 55and extend over and around the guiding support 55. They pass throughnotches or openings 55 to a point beyond the face of the support whenthe parts are swung to their extreme left hand osition (see Fig. 2), Theposition of the ever 61 with relation to the operating lever 35 andconsequently the normal position of the guiding supports may bedetermined by an adjustable stop in the upper end of the lever 35, suchstop conveniently taking the form of a set screw 64.

The severed section of the lead or rule strip drops down upon a pivotedor swinging section 60 of the receiving table or ga ley, and in order tostack the successive sections and move them out of the path' of sueceeding sections, a rocker 62 is pivotally mounted in bearings in theframe 15 and arm 18, respectively, said rocker being profrom theposition parts is such that, r

vided with a series of projections 62', which, when the, rocker isoperated, will oscillate back and forth to the full and dotted linepositions shown in Fig. 2. When turned to the full line position, theprojections 62 will push the sections of lead or rule strip forwardly,as indicated in Fig. 9, and when turned back to the dotted line positiona space is left for the reception of a succeeding section of strip, oneof which latter is shown in dotted lines as descending to the table inFig. 2, at 65. For operating the rocker 62, it is conveniently providedwith a rearwardly projecting arm 66, Fig. 3, connected by a link 67 withthe bell crank operating lever 39 atr a point forward of the axis of thelever. The link 67 may, if desired, be a yielding link, or embody in itsconstruction a well known form of spring box 68. The downward movementof the forward end of the operating bell crank lever 39 serves to turnthe rocker rearwardly to withdraw the projection 62 from the path of thedescending section of strip, and

the upward movement of the bell crank lever 39 returns the parts totheir normal position and pushes the stack of leads or rules forwardlyover the table 60. The pivoted section of the table is hung on therocker 62 and is provided with a forwardly extended pro ection 60adapted to cooperate with the edge of the fixed section 60 of the table,and a spring 69 'is provided for turning the pivoted section 60 up outof the way when the melting pot is lowered for the purpose of inspectionor for other reason during the adjustment of the machine. The pivotedsection 60 of the table or galley thus moves with the shearing orcutting mechanism, while a fixed section 60 remains in position in frontof the said mechanism, just as does the galley or table of the ordinaryMonotype casting machine.

The operation of the apparatus will be readily appreciated from theforegoing de- SCIl tion. The operator having determined the ength of thesections of the lead or rule I strip he desires, sets the adjustablecollar 27 on the rod 26 at the proper point to give the desired distancebetween the gage or projection 31 and the fixed cutter or cooperat- 111gedges of the fixed and movable cutters, and should the. length of stripldesired be greater than can be secured by t e use of the gage 31, thelatter is turned out of the wa and the gage 32 employed. The strip is avanced intermittent y owing to the fact that it is cast in sections, andeach section ad-' vanced before the next section is cast.

The operating mechanism for the operating lever 14 as well as the 0rating mechanism for the lever 5 whic advances the mold blade all derivemotion from the same drive shaft, with the result that by properlypositioning the cams, the two levers are caused to move in a pro 1'sequence, the lever 14 moving downward y at its outer end while the moldblade is being retracted or is at rest, and owing to this relationshipit is ossible to effect the severance when the strip is stationary.Assuming that the strip has advanced with a jump, causing an overthrowof the sliding cutter frame, the latter will settle back to its correctposition for making the out before the operating lever will move theparts to effect the cut. With the arrangement described it has beenfound possible to cut the strip into sections which are within thepermissible variation from absolute standard in printers make-up work,and inasmuch as the machine is entirely automatic in its action, it mabe set to cast and cut definite lengths an when once set in operation,requires little or no further attention.
